Ceylon cinnamon is considered safe to consume in daily amounts ranging from 0.5 grams up to 3 grams per day for up to 6 months. It contains only trace amounts of coumarin, a compound that in higher doses found in cassia cinnamon may cause liver damage. Thus, Ceylon cinnamon can be consumed at these levels without major risk of toxicity.
Safe Daily Intake Guidelines
- Ceylon cinnamon doses of 0.5 to 3 grams daily are possibly safe for up to 6 months of use.
- Unlike cassia cinnamon, Ceylon cinnamon has negligible coumarin content, making it safer for regular consumption.
- The general recommendation aligns with about ½ to 1 teaspoon (approximately 2-4 grams) per day, though staying at or below 3 grams is advisable.
Safety Considerations
- Higher doses over long periods lack sufficient data for safety assurance.
- Pregnant or breastfeeding people should stick to food amounts, avoiding medicinal or supplemental doses.
- If surgery is planned, it's recommended to stop cinnamon intake at least two weeks prior as it may affect blood sugar and blood pressure control.
In summary, consuming up to 3 grams of Ceylon cinnamon daily is generally safe for adults, but long-term high-dose use should be approached cautiously.
